Patented July 1, 1930- UNITED STATES- PATENT OFFICE WALTER E. LAGEY, OFSPRINGFIELD, OHIO; ASSIGNOR, BY MESNE ASSIGNMENTS, TO

FRIGIDAIRE CORPORATION, OF DAYTON, OHIO, A CORPORATION OF DELAWARE IBEFRIGERATING APPARATUS vApplication fll ed. September 2, 126.- Serial1T0. 188,197.

This"invention relates torefrigerating apparatus of the compressor type,it more particularly relating to the condenser for the refrigerant andthe cooling means for thesame. I

One of .the objects of the invention is to improve the construction ofthe condenser coil to provide a coil which will have an increasedcapacity over other coilsoccupying the same space.

- A further object of theinvention is to provide a condensing coil soconstructed and arranged in connection with a cooling fan to provide foran effective cooling 'of thecoils.

Other objects will appear from the accompanying description and claims.

Referring to the drawings:

Fig. 1 is a plan view of an apparatus embodymg my improvements.

- Fig. 2 is a side elevation of the same. Q

Fig. 3 is a vertical section through a portion of the condensing coil.

Referring to the drawings, 1 represents a cfim ressor, 2 a pulley on theend of the s a The improved condenser is supported on the base 6 betweenthe motor and compressor and consists of a coiled pipe the turns 7ofwhich are projected inwardl on four sides preferably on a curve as inicated at -7 so that each coil turn will present somewhat of a starshape. The condenser ,coil

is supported in the following manner:

Four equally spaced metallic straps 8 are provided, the lower ends ofwhich are bent at right angles to form feet 9 secured to the base 6,while the upper ends thereof are likewise. bent at right angles asindicated at 10, and extend to the center ofthe coil where they areunited-by a belt or screw 11. Referring more particularly to-Fig. 3,

' there is. also associated with each strap --8 a clamping: bar 12secured tothe s'trap screws-13 and haying rounded recesses 14 thereof, 3an electric motor, 4 a pulley on the end of the shaft of the motor, and5 a belt running from the pulley 4 to the to receive the bent portions 7.of the coil turns so that the coil may be firmly clamped to the straps.

A cooling fan 15 has its shaft mounted in a bearing at the upper end ofthe standard 16, the lower end of which is adjustably mounted on adovetail groove formed in a bracket 17 on the base 6 andadjustably heldthereon by a screw 18 which extends through a slotted opening 19 inthestandard so that the standard may be adjusted 'as to height. Theshaft 20 of the. fan has a pulley 21 over which passes the belt- 5, theadjustment described permittin the pulley to be adjusted in proper"relatlonto the belt.

By having the coil of the condenser formed as described, it will be seenthat a greater capacity for the refrigerant is secured over a coil ofusual form occupying the same space. Further, by so formin the coils itwill be seen that all sides 0 each coil will be placed in the path ofthe air current from the fan so as to secure a greater cooling effect.

' Having thus described 7' my invention, I

claim 1. In refrigerating apparatus a condenser including a(plurality ofsubstantially square loops space apart verticall and arranged in astack, a plurality of said loops havlng adjacent sides bent inwardly topresent convex surfaces to he longitudinal axis of the condenser, anmeans for supporting the loops in said-irertically spaced relation.

2. In refrigerating a paratus, a condenser including a lurality ofsubstantially square loops spaced apart-verticall and arranged in astack, a plurality of said loops having all four sides curved inwardl topresent convex surfaces to the vertica axis of the condenser and meansfor supporting the loops in said spaced relation substantially asdescribed.

3. In refrigerating apparatus, an air cooIed condenser including asingle continand arran ed in a stac each loop having 'uous conduit bentto form a. plurality .of substantially square s, vertically spacedconvex surfaces to the vertical axis of the oondenser, means forsupporting the loops 1n sald vertical spaced relation and means forforcing air over the said loops.

In testimony whereof I have hereunto set my hand this th day of August,1926.
